Mistakes are easilly made. I have a routine I follow, before I go upstairs to bed, even if anyone else is still up downstairs, I check that all doors and windows are locked. But I awoke one morning to find my sliding glass door was unlocked and with the security bar removed. Only then did I vaguely recall getting up at 0300 to let a wining dog outside to relieve an upset stomach. In my sleepy state I neglected to secure the sliding glass door before going back to bed.
